What is an electromagnetic field?Electromagnetic fields are something. ？

Electromagnetic field concept:

It is an intrinsically related and interdependent unity and general term for electric and magnetic fields. The electric field that changes with time produces a magnetic field, and the magnetic field that changes with time produces an electric field, and the two are causal to each other to form an electromagnetic field. Electromagnetic fields can be caused by charged particles moving at variable speeds, or by electric currents that vary in intensity, and regardless of the cause, electromagnetic fields always travel around at the speed of light, forming electromagnetic waves.

The electromagnetic field is the medium of electromagnetic action, has energy and momentum, and is a form of matter being. The properties and characteristics of the electromagnetic field and the law of its motion are determined by Maxwell's equations.

For example, there is a magnetic field at the poles of a magnet, and magnetic field lines are an idealized way to understand the magnetic field.

Both the electric field and the magnetic field are generated by electric charges, and their magnitude and direction are related to the distance from the charge, and both are related to the size of the charge, but the difference is that the magnetic field is also related to the speed of the charge. In addition, electromagnetic and magnetic fields can generate each other. From the point of view of three-dimensional space, the biggest difference between the two is whether it is related to speed.

But from the perspective of four-dimensional space-time, it is different. Go and learn the wonderful special theory of relativity, which will tell you that the electromagnetic field is just a different manifestation of an inseparable thing, there is no essential difference, just like a cube, which looks like a square from one side, turns one angle and becomes two rectangles, and another angle can be three diamonds. These three different two-dimensional shapes are superficially different, but in essence they are just a cube – just one thing, no difference at all!

An electric field is a special substance that exists in the space around an electric charge and a changing magnetic field. The electric field is different from ordinary physical objects, it is not composed of molecular atoms, but it exists objectively, and the electric field has objective properties such as force and energy that ordinary substances have. The nature of the force of the electric field is manifested as:

The electric field has a force on the charge placed in it, and this force is known as the electric field force. The energy property of the electric field is shown as follows: when the charge moves in the electric field, the electric field force does work on the charge (which indicates that the electric field has energy).

The magnetic field is a special substance that cannot be seen or touched, and the magnetic field is composed of atoms or molecules, but the magnetic field exists objectively. The magnetic field has the radiative properties of wave particles. There is a magnetic field around the magnet, and the interaction between the magnets is mediated by the magnetic field, so the two magnets can act without contact.

An electric current, a moving charge, a magnet, or a special form of matter that exists in the space around the changing electric field. Since the magnetism of a magnet is the same as the current, the current is the movement of an electric charge, so in a nutshell, the magnetic field is generated by the change of the moving charge or electric field. From the point of view of modern physics, the only ultimate components that can form charges in matter are electrons (with a unit negative charge) and protons (with a unit of positive charge), so the negative charge is a point-by-point object with excess electrons, and the positive charge is a point object with excess protons.

The real source of the magnetic field generated by the moving charge is the magnetic field of the bridge generated by the moving electrons or the moving protons. For example, the magnetic field generated by an electric current is the magnetic field generated by electrons moving in a wire.

The electromagnetic field is a special substance with a very small mass, which fills the universe and is also occupied by this special substance in the previously said vacuum.

1. Personal magnetic field: Just as an electric current produces a magnetic field, the human body itself also produces a magnetic field. The magnetic field generated by magnets and electric currents attracts metals such as iron, cobalt, and nickel, and the human heart's electrocardiogram also produces a magnetic field to attract the things you imagine and focus on in your heart.

2. The human heart is pure, there is no boundary in the pure heart, the pure heart is equal, and all the Buddhas in the ten Dharma realms are like this, and the quiet power of that induction is very strong.

3. This kind of thing, modern science has also proved that our Buddhism is called induction, and now science is called magnetic field. Each of us has a magnetic field, and the function and force of the magnetic field are different.

4. A person with a pure heart and a person who really has practice, his magnetic field is very strong, and if he is a person with many delusions, distracting thoughts, and troubles, his magnetic field is very weak.

5. There is a new term in China, called special function, and our Buddhism is called supernatural power. People with special abilities can see light and qi in people's bodies. Light and air are different in color and size, but in fact, it is the energy of the magnetic field as mentioned in science.

6. The living environment is the same, if this dojo is a Fa-rectification dojo, and a person with special functions can see that the qi of this dojo is very strong and strong, and the energy of the magnetic field is different in the dojo of the abbot's Fa-rectification dojo.

7. In some places, as soon as you walk in, you will feel eerie and terrifying, and the magnetic field of that place is different. Corresponding to the magnetic field of our own goodness, it is very comfortable; If you don't, it's very uncomfortable, that's the truth.
